“I always think of a guest room as an opportunity to use a color that doesn’t appear anywhere else in the house,” says designer Ashley Whittaker. “It helps make it memorable and distinct.” Here, it was a punchy citrus yellow, which she spotted in a fabric from Schumacher and then used as bed upholstery and a Roman shade. The Noguchi lantern helps make the room’s high ceilings feel less cavernous. “The pendant works because it’s big, but the design of it is simple and not overwhelming,” says Whittaker. The wallpaper is by Meg Braff.
